Review
INTRODUCTION
The incidence of duodenal perforation after ERCP ranges from 0.09% to 1.67% and mortality up to 8%.
METHODS
This systematic review was registered in Prospective Register of Systematic Reviews, PROSPERO. Stapfer classification of ERCP-related duodenal perforations was used.
RESULTS
The systematic search yielded 259 articles. Most frequent post-ERCP perforation was Stapfer type II (58.4%), type I second most frequent perforation (17.8%) followed by Stapfer type III in 13.2% and type IV in 10.6%. Rate of NOM was lowest in Stapfer type I perforations (13%), moderate in type III lesions (58.1%) and high in other types of perforations (84.2% in type II and 84.6% in IV). In patients underwent early surgical treatment (<24 h from ERCP) the most frequent operation was simple duodenal suture with or without omentopexy (93.7%). In patients undergoing late surgical treatment (>24 h from ERCP) interventions performed were more complex. In type I lesions post-operative mortality rate was higher in patients underwent late operation (>24 h). In type I lesions, failure of NOM occurred in 42.8% of patients. In type II failure of NOM occurred in 28.9% of patients and in type III there was failure of NOM in only 11.1%, none in type IV. Postoperative mortality after NOM failure was 75% in type I, 22.5% in type II and none died after surgical treatment for failure of NOM in type III perforations.
CONCLUSIONS
This systematic review showed that in patients with Stapfer type I lesions, early surgical treatment gives better results, however the opposite seems true in Stapfer III and IV lesions.

Meta-Analysis Review
This systematic review and meta-analysis evaluates metabolic and anthropometric outcomes of duodenal-jejunal bypass liners (DJBLs) compared to optimal medical management for the treatment of obesity and its associated metabolic complications. A systematic search of MEDLINE, Embase, Scopus, and Web of Science databases was conducted. Studies were reviewed and data were extracted following the PRISMA guidelines. The primary outcome was glycated hemoglobin (HbA1c) change at device explant with secondary outcomes including body mass index (BMI), weight, fasting plasma glucose (FPG), and adverse events. Twenty-eight studies met inclusion criteria evaluating a total of 1229 patients undergoing DJBL treatment. When compared to medical management, DJBLs provided superior reductions in HbA1c (mean difference, MD -0.96%; 95% CI -1.43, -0.49; p < 0.0001), FPG (MD -1.76 mmol/L; 95% CI -2.80, -0.72; p = 0.0009), BMI (MD -2.80 kg/m ; 95% CI -4.18, -1.41; p < 0.0001), and weight (MD -5.45 kg; 95% CI -9.80, -1.09, p = 0.01). Post-explant data reveals a gradual return to baseline status. Incidence of early device explant was 20.2%. Complications were resolved conservatively or with device explant without long-term morbidity or mortality. We conclude that DJBLs provide significant metabolic and anthropometric improvements for patients with obesity. Uncertainty about the extent to which improvements are maintained after device removal may limit the use of DJBLs as a standalone treatment for obesity and associated metabolic complications.

BACKGROUND
Inflammatory bowel disease, including ulcerative colitis, microscopic colitis, and Crohn's disease (CD), has a global impact. This review focuses on duodenal CD (DCD), a rare subtype affecting the duodenum. DCD's rarity and asymptomatic nature create diagnostic challenges, impacting prognosis and patient well-being. Delayed diagnosis can worsen DCD outcomes.
AIM
To report a rare case of DCD and to discuss the diagnostic challenges and its implications on prognosis.
METHODS
A systematic literature search, following the PRISMA statement, was conducted. Relevant studies were identified and analysed using specific Medical Subject Terms (MeSH) from PubMed/MEDLINE, American Journal of Gastroenterology, and the University of South Wales database. Data collection included information from radiology scans, endoscopy procedures, biopsies, and histopathology results.
RESULTS
The review considered 8 case reports and 1 observational study, involving 44 participants diagnosed with DCD, some of whom developed complications due to delayed diagnosis. Various diagnostic methods were employed, as there is no gold standard workup for DCD. Radiology scans [magnetic resonance imaging (MRI), computed tomography (CT), and upper gastrointestinal X-ray], endoscopy procedures (colonoscopy and esophagogastroduodenoscopy), biopsies, and clinical suspicions were utilized.
CONCLUSION
This review discusses DCD diagnosis challenges and the roles of CT, MRI, and fluoroscopy. It notes their limitations and compares findings with endoscopy and histopathology studies. Further research is needed to improve diagnosis, emphasizing scan interpretation, endoscopy procedures, and biopsies, especially in high-risk patients during routine endoscopy.

Meta-Analysis Review
Oxidative stress (OS) constitutes a pivotal factor in the initiation and progression of lipopolysaccharide (LPS) challenges in broiler chickens. Increasing studies have demonstrated that Alleviation of oxidative stress seems to be a reasonable strategy to alleviate LPS-mediated afflictions in broilers. Nonetheless, the relationship between OS-related indicators and exposure to LPS remains a topic of debate. The aim of this investigation was to precisely and holistically evaluate the effect of LPS exposure on OS-associated markers. We conducted a systematic search of four electronic databases-PubMed, Web of Science, Scopus, and Cochrane for relevant studies, and a total of 31 studies were included. The overall results showed that the LPS treatment significantly increased the levels of oxygen radicals and their products, such as malondialdehydes (MDA), reactive oxygen species (ROS), and 8-hydroxy-2-deoxyguanosine (8-OHdG), while significantly reduced the levels of antioxidants, such as total antioxidative capacity (T-AOC), total superoxide dismutase (T-SOD), catalase (CAT), glutathione peroxidase (GSH-Px), and glutathione (GSH), in the chickens. Intriguingly, though the observed trends in alterations were not strictly correlated with LPS concentrations, the enzyme activity levels were indeed influenced by the concentration of LPS. This observation highlights the complex relationship between LPS exposure and the body's antioxidant response. Despite some limitations, all the included studies were deemed credible. Subgroup evaluations revealed that the jejunum and duodenum has demonstrated stronger antioxidant capability compared to other tissues. Overall, our study presents compelling evidence that exposure to LPS induces significant OS in chickens. And we also found that the extent of OS was related to LPS doses, target tissues, and dietary ingredients.

Review
BACKGROUND
Owing to the possibility of weight regain after the long-term follow-up of gastric bypass patients and because of the high morbidity of biliopancreatic diversion with duodenal switch, single-anastomosis duodeno-ileal switch (SADIS) has emerged as a rescue procedure in bariatric surgery.
OBJECTIVE
The purpose of this review is to summarize the literature data on SADIS.
SETTING
University Hospital, NY.
METHODS
A comprehensive literature review was performed through October 2016 to identify English studies on SADIS performed in human subjects. Outcomes of interest were technical considerations, postoperative complications, weight loss outcome, comorbidity resolution rate, and nutritional deficiency after SADIS.
RESULTS
A total of 12 studies including 581 SADIS patients (217 males and 364 females) were included. SADIS was a primary procedure in 508 patients (87.4%) and a conversion procedure in 73 patients (12.6%). The length of common limb was 300 cm in 54.2%, 250 cm in 23%, and 200 cm in 13.4% of patients. Anastomosis technique was a linear stapler in 26.7% and a hand sewn suture technique in 73.3% of patients. Diarrhea was the most common complication (1.2%). The average %EWL was 30% at 3 months, 55% at 6 months, 70% at 1 year, and 85% at 2 years. Co-morbidity resolution rate was 74.1% for type 2 diabetes mellitus, 96.3% for hypertension, 68.3% for dyslipidemia, 63.3% for obstructive sleep apnea, and 87.5% for GERD. Overall, vitamin A, selenium, and iron deficiency were the most common nutritional deficiencies with the possibility of the protein malnutrition in up to 34% of the patients when measured.
CONCLUSION
As a modified bariatric procedure, SADIS has promising outcomes for weight loss and comorbidity resolution in morbidly obese patients. When measured, there was a high prevalence of macro-nutrient deficiencies following SADIS. There is a high technical variability, and long-term data are required before any meaningful conclusion can be made.

Meta-Analysis Review
BACKGROUND AND AIM
Accurate preoperative staging of ampullary neoplasms is of paramount importance in predicting prognosis and determining the most appropriate therapeutic approach. The aim of the present review was to evaluate the accuracy of endoscopic ultrasound (EUS) in predicting depth of ampullary tumor invasion (T-stage) and regional lymph node status (N-stage) by carrying out a meta-analysis of all relevant studies.
METHODS
We systematically searched PubMed, Medline and Scopus databases for all studies published between January 1980 and December 2012. Only EUS studies involving ≥ 10 patients with ampullary neoplasms, confirmed by surgical histopathology, with data available for construction of a 2 × 2 table were included.
RESULTS
Meta-analysis of 14 studies involving 422 patients using the Mantel-Haenszel method was performed. Pooled sensitivity and specificity of EUS to diagnose T1-stage tumor were 77% (95% CI: 69-83) and 78% (95% CI: 72-84), respectively. Pooled sensitivity for T4 tumors was 84% (95% CI: 73-92) and specificity was 74% (95% CI: 63-83). Combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio for diagnosing nodal status were 0.70 (95% CI: 0.62-0.77), 0.74 (95% CI: 0.67-0.0.80), 2.49 (95% CI: 1.91-3.24), 0.46 (95% CI: 0.36-0.59) and 6.53 (95% CI: 3.81-11.19), respectively.
CONCLUSION
Based on our pooled estimates, EUS had a moderate strength of agreement with histopathology in preoperative staging of ampullary neoplasms in predicting tumor invasion and lymph node involvement. Additional refinement in EUS technologies and diagnostic criteria may be required to enhance staging accuracy.

Meta-Analysis
OBJECTIVE
To explore the outcomes and prognostic factors associated with fetal megacystis (enlarged bladder).
STUDY DESIGN
The MEDLINE and EMBASE databases were searched for studies reporting on outcomes of fetal megacystis. The outcomes observed were chromosomal abnormalities, associated structural anomalies, spontaneous resolution, and survival rates. We also evaluated the potential role of fetal gender, oligohydramnios, gestational age at diagnosis, and intrauterine intervention as prenatal prognostic factors.
RESULTS
The search identified 558 articles in total, and 13 studies (1675 fetuses) were included in this systematic review. The overall incidences of chromosomal abnormalities and associated structural anomalies in fetal megacystis were 10% and 24%, respectively. Spontaneous resolution of megacystis occurred in 32% of fetuses, and 44% of fetuses were born alive and survived until the follow-up. The odds ratio of survival with oligohydramnios was 0.14, and the mean difference in gestational age at diagnosis between survival and non-survival was 3.43 weeks. No significant difference in survival rate was observed between the genders, and an intrauterine intervention did not significantly improve the prognosis.
CONCLUSIONS
A considerable proportion of fetuses with megacystis are born with a good prognosis. Oligohydramnios and lower gestational age at diagnosis are associated with worse outcomes.

Meta-Analysis
Long-term Metabolic Morbidity and Steatohepatosis Following Standard Pancreatic Resections and Parenchyma-sparing, Local Extirpations for Benign Tumor: A Systematic Review and Meta-analysis.
OBJECTIVE
To assess metabolic dysfunctions and steatohepatosis after standard and local pancreatic resections for benign and premalignant neoplasms.
SUMMARY OF BACKGROUND DATA
Duodenopancreatectomy, hemipancreatectomy, and parenchyma-sparing, limited pancreatic resections are currently in use for nonmalignant tumors.
METHODS
Medline, Embase, and Cochrane libraries were searched for studies reporting measured data of metabolic functions following PD, pancreatic left resection (PLR), duodenum-sparing pancreatic head resection (DPPHR), pancreatic middle segment resection (PMSR), and tumor enucleation (TEN). Forty cohort studies comprising data of 2729 patients were eligible.
RESULTS
PD for benign tumor was associated in 46 of 327 patients (14.1%) with postoperative new onset of diabetes mellitus (pNODM) and in 109 of 243 patients (44.9%) with postoperative new onset of pancreatic exocrine insufficiency measured after a mean follow-up of 32 months. The meta-analysis displayed pNODM following PD in 32 of 204 patients (15.7%) and in 10 of 200 patients (5%) after DPPHR [P < 0.01; OR: 0.33; (95%-CI: 0.15-0.22)]. PEI was found in 77 of 174 patients following PD (44.3%) and in 7 of 104 patients (6.7%) following DPPHR (P < 0.01;OR: 0.15; 95%-CI: 0.07-0.32). pNODM following PLR was reported in 107 of 459 patients (23.3%) and following PMSR 23 of 412 patients (5.6%) (P < 0.01; OR: 0.20; 95%-CI: 0.12-0.32). Postoperative new onset of pancreatic exocrine insufficiency was found in 17% following PLR and in 8% following PMSR (P < 0.01). pNODM following PPPD and tumor enucleation was observed in 19.7% and 5.7% (P < 0.03) of patients, respectively. Following PD/PPPD, 145 of 608 patients (23.8%) developed a nonalcoholic fatty liver disease after a mean follow-up of 30.4 months. Steatohepatosis following DPPHR developed in 2 of 66 (3%) significantly lower than following PPPD (P < 0.01).
CONCLUSION
Standard pancreatic resections for benign tumor carry a considerable high risk for a new onset of diabetes, pancreatic exocrine insufficiency and following PD for steatohepatosis. Parenchyma-sparing, local resections are associated with low grade metabolic dysfunctions.

Meta-Analysis Review
OBJECTIVE
Comparison of effectiveness between the pylorus-preserving pancreaticoduodenectomy ("pylorus-preserving Whipple" [PPW]) and the classic Whipple (CW) procedure.
METHODS
A systematic literature search (Medline, Embase, Cochrane Library, Biosis, Science Citation Index, Ovid Journals) was performed to identify all eligible articles. Randomized controlled trials (RCTs) comparing PPW versus CW for periampullary and pancreatic carcinoma were eligible for inclusion. The methodologic quality of included studies was evaluated independently by 2 authors. Quantitative data on perioperative parameters (blood loss, transfusion, operation time, and length of hospital stay), mortality, morbidity, and survival were extracted from included studies for meta-analysis. Pooled estimates of overall treatment effect were calculated using a random effects model.
RESULTS
In total, 1235 abstracts were retrieved and checked for eligibility and 6 RCTs finally included. The critical appraisal revealed vast heterogeneity with respect to methodologic quality and outcome parameters. The comparison of overall in-hospital mortality (odds ratio, 0.49; 95% CI, 0.17 to 1.40; P = 0.18), morbidity (odds ratio 0.89; 95% CI, 0.48 to 1.62; P = 0.69), and survival (hazard ratio, 0.74; 95% CI, 0.52 to 1.07; P = 0.11) showed no significant difference. However, operating time (weighted mean difference, -68.26 minutes; 95% CI, -105.70 to -30.83; P = 0.0004), and intraoperative blood loss (weighted mean difference, -766 mL; 95% CI, -965.26 to -566.74; P = 0.00001) were significantly reduced in the PPW group.
CONCLUSION
Hence, in the absence of relevant differences in mortality, morbidity, and survival, the PPW seems to be as effective as the CW. Given obvious clinical and methodological interstudy heterogeneity, efforts should be intensified in the future to perform high quality RCTs of complex surgical interventions on the basis of well defined outcome parameters.

Meta-Analysis
OBJECTIVE
Our systematic review aims to compare recurrence rates and complications of biological versus synthetic patches for the repair of congenital diaphragmatic herniae.
METHODS
Studies from January 1, 1980 to April 25, 2020, with patients under the age of 16 years and with a minimum 6-month follow-up, were included from MEDLINE, Embase, and Cochrane databases. Funnel plots for recurrence rates were constructed for biological and synthetic patches. Subgroup analysis was performed for recurrence rate at the 1-year time-point and data were gathered on individual adverse events from relevant studies.
RESULTS
A total of 47 studies with 986 patients (226 biological, 760 synthetic) were included. Funnel plot analysis determined overall recurrence rates of 16.7% for synthetic and 30.3% for biological patches. Subgroup analysis of 493 and 146 patients with synthetic and biological patches, respectively, showed recurrence rates of 9.9 and 26%, respectively.The most commonly used patch types-PTFE (polytetrafluoroethylene) and SIS (small intestinal submucosa)-had 11.5 and 33.3% recurrence, respectively. Adhesive bowel obstruction rates ranged from 4 to 29% in studies that systematically reported it for synthetic, and 7 to 35% for biological patches. Gastroesophageal reflux rates ranged from 25 to 48% in studies that systematically reported it for synthetic, and 21 to 42% for biological patches. Pectus deformity rates were reported as high as 80% for synthetic patches.
CONCLUSION
Biological patches appear to have higher recurrence rates than synthetic patches, while skeletal deformities are associated more commonly with synthetic patches. Results of biological patches are mainly using SIS and this may overestimate complications of current superior biological patches.
